Said handle is mounted fast u none end of the pin P assing axiallyt ugh the ivot member the other end of this pin eing en aged by a springclip Q, (such said clip of said pin as is best s own in Figure 5),

reventing any axial shifting m its oper position in the assembly. Thepin is formed with a lurality of uniformly s aced longitudina teeth Eadapted for est motion engagement with teeth S formed upon the members.H and or romno, omo, nssrcnon are run rm comm, or

The effect of saispring V- upon the pin P isto maintain the teeth R of said pin normallsubstantially of the pivot of rotation before a driving engagement isestablished between'the'pin and pivot memher. As shown in Figure 4 thepin P has been given its initial rotation in the direc- 'tion ofthearrow, the lost motion between. said pin and pivot member having been{taken up and the detent bar M having been retracted during suchlostmotion move-' ment so that the pivot member is free to be rotativelyactuated by said pin upon a further turning of the handle in its itialdirection.

Counterbalancing means for the sliding window member is provided as iscustomary, the illustrated means consisting in a coiled spring W securedwithin the chamber D to the door upright opposite to that upon which thebracket F is mounted, said spring bein connected through an anchoragemembar to a semi-circular bar X mounted upon the pivotal end of thecontrol arm E and-partially embarcing the bearing portion of saidbracket;

The described construction is adapted to be manufactured at acomparatively low expense and may be very quickly assembled. The use ofa single spring to project both detent bars M, M is a desirable featureof the construction as is also the employment of bar material to formsaid detents, requiring ve litle machinin One of the most desirab e.features of t e construction. lies Linthe use of a very light s ring toproject the two detent bars, this eature securing the advantage that theclicking noise when the mechanism is operated is ne ligible. In theprior art where a detent or detents have been employed in a similarconnection, the spring projecting the same has been also employed tomalntain the neutral position of the actuating handle. Applicant employsa separate spring V to maintain the handle be in neutral position and isthereby enabled to use a very light spring forthe detent bars. Theelimination of clicking further follows from the use of a single springN to project both detents for the reason that the withdrawal ofeither'detent, preliminary to rotation of the pivot member, acts toconsiderably relieve the other detent from the stress of the spring N,since the latter is compressed by the retracted detent. The formation ofthe pivot member H in two parts respectively formed with flangesengaging opposite sides of the bracket F is a atm member.

In combination, a stationarybear1ng,, -an arm, a two-part pivot member ournaled in and extendingtransversely of said bear-- ing, and means for clamping the parts of jthe pivot member in assembled relation and also securing said arm in vfixed relation to thepivot member; i 2. In combination, a bearing, and apivot member journ'aled in said bearing, a pair 01- 1 detent memberscarried by the pivot member and adapted to project into engagement 'tionof the pivotmember, azcommon spring" for rojecting said detents,-anactuating mem r for said pivot member, and means for retracting one orother of said "detents upon .initial movement of said actuating memberaccording to the-direction of, actu-. ation thereof.

3. In combination, a bearing, and a pivot member journaled in saidbearing, a. pair I of detents mounted in said pivot member andrespectively engageable ina projected position with the bearing toreversely oppose rotation of the pivot member, a com-' said detents, an
